PDF-What is HEPA

HEPA is an acronym for High Efficiency Particle Arrestor Basically HEPA is a type of filter that can trap the smallest particles 03 micrometers m in diameter that other air filtration systems would si.

You wouldn't know and if you were to get sick, it may not be related, but you wouldn't know."~ Susan Michaelis, Former Pilot of Qantas Airlines [1]. ID 68 Question How are HEPA filters certified? Answer Test procedures for HEPA filters are discussed in 20 1 6 ASHRAE Handbook - HVAC Systems and Equipment , Chapter S2 9 . Certification ma y M any articles try to compare HEPA and E lectrostatic filtration. It seems that every article chooses one or the other rather than comparing the two. Sometimes HEPA is the clear choice for a filtra Why is the testing done with a 0.3-that 0.3-microns is the "Most Penetrating Particle Size (MPPS)" for HEPA filter media. Efficiency is typically than 0.3 microns are typically more easily trapped, or Low pressure drop design M-Series HEPA is designedfor value, versatility, and performance.

RP02.08. Standardized Task Evaluation Program. The Standardized Task Evaluation (STE) program promotes a work-ready workforce through the standardization of common tasks by defining the knowledge and skills required to perform a given task. Subject Matter Experts (SMEs) analyze the task and generate lesson plans, knowledge examination, and performance evaluation elements. These elements are combined to create an STE package. . 113 • clean and decontaminate them after use.
